Definitions

  • the invention relates to a method for dosing a paste-like thixotropic detergent in a commercial washing machine in particular by means of a dosing device, wherein one 1) place the sales container or a part of it filled with the detergent in a receptacle of a dosing device and open it on the underside and 2) pressurize the detergent with volume control from above.
  • volume controlled is a control depending on To understand the target volume of the paste emerging from the container.
  • Paste-like, essentially water-free detergents are mainly used in commercial laundries. Examples of such pastes are described in DE 38 26 110 A1 and described in DE 37 19 906 A1. The advantages are in the high Washing power due to the high concentration of detergent components Powdered detergents, as washing active, only the conditioning of Detergent additives are not required here.
  • a plate that moves in the barrel and closes close to the barrel walls also called the follower plate, lies on the paste and enables the Delivery via a simple pipeline with a suction pump (DE 37 19 906 A1 and DE 38 26 110 A1).
  • the removal process is suitable for pastes with a viscosity at about 75,000 to 90,000 mPa s.
  • Viscosities e.g. B. from 150,000 to 250,000 mPa s is in the G 93 14 591 a stirrer below the follower plate suggested that the immediately The paste located below the follower plate liquefies and so one easily accessible.
  • the follower plate according to the prior art does not exert any pressure on the paste out.
  • a promotion of the paste is only a special strong suction pump.
  • the use of such an expensive pump is only economical with relatively large containers.
